Overcurrent circuit breaker, 6kA BKJ63Nd series 3P 20A characteristic C BKJ63Nd 3P C20 BKJ63ND 3P C20

Overcurrent circuit breaker BKJ63Nd 3P C20 is a reliable protection for electrical installations, designed for both domestic and industrial applications. The device effectively protects circuits against the effects of overloads and short circuits, ensuring safety and longer life of connected devices. Manufactured by the renowned LS Electric, this circuit breaker combines high quality workmanship with advanced technical solutions.

Characteristics and application

The BKJ63Nd circuit breaker is characterized by a rated current of 20A and a C characteristic, which means it allows for short-term overloads without unnecessary tripping. This is particularly important when connecting devices with electric motors or other loads with high starting current. The three-pole design (3P) makes the circuit breaker perfect for three-phase installations, providing comprehensive protection. DIN rail mounting simplifies and speeds up installation, and the compact dimensions allow for efficient use of space in the switchgear.

The BKJ63Nd series circuit breakers are the successor to the popular BKN series, offering improved technical parameters and a more convenient solution in the form of a separate terminal for the wire and busbar. This makes installation faster and more precise. The device finds application in residential construction, commercial buildings and industry - wherever reliable protection of the electrical installation is required.

Advantages and structural features

• High short-circuit breaking capacity: 6kA guarantees effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage and fire.
• C characteristic: ideal for protecting circuits with loads with high starting current (e.g. motors, transformers). Allows for momentary exceeding of the rated current without unnecessary tripping.
• Three-pole design (3P): provides full protection in three-phase installations.
• DIN rail mounting: simplifies and speeds up installation and replacement of the circuit breaker.
• Wide operating temperature range: from -5°C to +40°C enables the use of the circuit breaker in various environmental conditions.
• Contact status visualization: allows for quick assessment of the circuit breaker status without the need for disassembly.
• Compliance with standards: meets the requirements of IEC 60898-1 and IEC 60947-2 standards, which guarantees safety and reliability.
• Solid construction: ensures long-lasting and trouble-free operation of the device.
• Adapted for conductors with a cross-section of: 1…25mm², which provides great flexibility when selecting cables for the installation.

The BKJ63Nd circuit breaker is an investment in the safety and reliability of your electrical installation - a choice proven by professionals!
